详情介绍：

The MRP-120 is a small portable meter for testing installations with AC type RCD. It measures all the important parameters of the installation including disconnection time and current, contact voltage and earth resistance. The test results can be stored in the internal memory and send to a computer via serial interface.

MRP-120 Technical Specifications

Testing AC residual current circuit breakers:
- measurement of tripping current I_A
- measurement of disconnection time t_A
- testing of standard and selective RCDs for the rated current values 10, 30, 100, 300 and 500 mA,
- testing current waveform: sinusoidal, selection of initial phase (0° or 180°),
- ability to measure touch voltage U_B and earth resistance R_E without tripping the circuit breaker,
- select safe voltage value threshold at 25V and 50V and additionally at 12.5V for selective RCDs,
- protection against exceeding the safe voltage setting during a measurement,
- detection of L and N leads swap and its automatic correction performed internally by the meter.
AC voltmeter function in the range 0...250V.
Rapid check of PE lead connection using a touch electrode.
Backlit LCD.
